CHUCK FR VEHICLE-WHEELS.

Specification of Letters Patent.

Patented J an. 4, 1916.

Applicationiled J' une 7, 1915. Serial No. 32,642.

improvements in checks Vfor vehicle wheels and more particularly thoseadapted for. use on an automobile and the primary object of theinvention is to provide an improved device of this character whereinthe` same may be releasably locked to any automobile wheel to preventthe wheel from being revolved theft of the machine. v

A further object of the invention is to provide a device which is simpleand durable in construction, inexpensive to manufacture, and one whichwill be very efficient in operation.

With these and numerous other objects in view my invention consists ofcertain novel features of construction, combination and arrangementl ofparts which willbe herein referred to and more particularly pointed outin the specification and claims.l

In the accompanying drawings: Figure 1 is a side velevation of myimproved device applied to an auto wheelz'Fig. 2 is a central verticallongitudinal section; Fig. 3 is a horizontal section on and, Fig. 4 is adetail vertical transverse section on the line 4-4 of Fig.

In describing my invention'I shall refer to the drawing in which similarreference characters., designate corresponding parts throughout theseveral views and in which the numeral 1 designates the body portionofthe chock having down turned side edges 2 adapted to fit the treadofva tire 3. The

side edges 2 of the body portion 1 have extensions 4 and 5, and an, arm7 is adapted to be pivoted on the'ektension 4 at 6 to engage the rim Sofan automobile wheel.

The opp osite eX ensi'on 5 of the body portion 1 is given a quarter turnnear one end as shownat 10 and has an aperture 11 in said end for apurpose to beniorefully described. The corresponding end of the arm 7has a longitudinally extending slot 9 through able others skilled -inthe art to which it`A whereby there can be no unauthorized useor theline3-3 of Fig. 2

which the end ofthe extension 5 is adapted to project when the arm is inclosed position. vA padlock v12 is adapted' to project through theaperture 1l to lock the parts in position. l

Projecting from the` outer edge of the body portion l is a radiallyextending centrally ldisposed spur 13 having a contracted lower endadapted to` be rigidly secured inv an 'aperture through the body.Reinforcing arch-shaped brace bars 14. and v15 are provided to rigidlysupport the spur 13 in operative position. The brace bar 14 whichcomprises -a metallic. rod extends Alongitudinally ofthe body portion 1andis secured at its ends 1 6 to 'the said body portionand its crown isadapted to project through an opening in the spur 13 as shown'at 18. Theother brace rod 15 whichis formed of a metallic strap extendstransversely of the body portion 1 and is secured at its ends 17 to thesame. This brace straphas its crown apertured at 19 so that the spur 13is adapted to project therethrough and said crown will be spacedslightly above wherethe brace rodl 14 projects through the spur.

In operation, when my improved chock is to be applied to one of thelwheels, of an automobile, the body portion 1. is ap lied to the tread 3ofthe tire and the arm is `'positioned to engage the rim 8 of tne wheelwhereby the longitudinal slot 9` in the end" of the arm 7 is'` adaptedto have'the end of the extension 5 project therethrough and the aperturein the end Wi'llbe spacedbe-` low the end of said arm. A padlock of anypreferred form is inserted throughjthe said aperture and locked therebylocking the chock firmly to the Wheel.

It will be obvious that any' accidental revolution of the .Wheel will beprevented, and even upon the application ofpower its progress will begreatly impeded, by reason of the radially projecting spur 13 ori/theouter surface 'of the body portion lof the chock. The. reinforcing.brace bars lsf'a'nd 15 enable the same to insure a safeandfpferfeetperformance of the aforesaid function'.

Unauthorized persons inv attempting to use the vehicle Will bepreventedfrom so doing by the chock, or even if they should attempt torun the vehicle the *irregular movement of the n iovemer'it` o ,render'detection a comp rative' c'eftanty.l` From the feregong, scription ofthe vhe'el will prevent any` y the machine, and A Willf construction ofmy improved device the manner of applying the same to use and theoperation thereof will be readily understood and it will be seen that Ihave provided a simple, inexpensive and efficient means for carrying outthe objects of this invention.

While I have particularly described the elements best adapted to performthe functions set forth, it is obvious that various changes in form,proportion and the minor details of construction may be resorted to,within the scope of the appended claims, without departing from thespirit or sacrificing any of the principles of the invention.

I claim as my invention:

l. A chock with a body adapted to releasably engage the tread of thetire of a wheel, a centrally disposed spur projecting radially from saidbody, a longitudinally eX- tending arch-shaped brace bar secured at itsends to said body and having its crown projecting through the spur, anda transversely Aextending arch-shaped brace bar secured at its ends tothe body and having its crown apertured to receive the said spur.

2. A chock with a body adapted to releasably engage the tread of a tireof the wheel, a centrally disposed spur projecting radially from saidbody, a longitudinally vl.extending arch-shaped metallic rod secured atits ends to said body adjacent the ends of the same, a transverselyextending archshaped metallic strap having its ends sel cured to saidbody adjacent the sides of the opening in the spur intermediate itsends, a

transversely extending metallic strap having its ends secured to saidbody adjacent the sides of the same and its crown portion apertured toallow' the spur to project theref through, and the crown portion of therod and strap engaging the spur at a point interinediate its ends andspaced from the body portion.

In testimony whereof l have hereunto set my hand in presence ofsubscribing witnesses.
